Mystery of the weird bed solved. I visited the factory yesterday, and today went for a test drive and found a salesperson in a different dealership who seemed more knowledgeable. Plus I took my tape measure. If you remember, the bed in the Fleetwood Tioga Ranger I have been looking at had a long, square piece of upholstered foam piece (bolster?) that fit into a space at the head of the bed in the bedroom slide.
So here is the story:
1) The mattress WITHOUT the bolster in place is 67" long and 60" wide, and fits perfectly on the platform.
2) The bed WITH the bolster in place is 72" long and 60" wide, but the mattress hangs over the foot of the bed slightly. Obviously, they added this extra piece of foam in order to end up with a 72" long bed.
3) The bolster is upholstered and does not have any welting, so it is smooth when it is in place. I don't think it will bother anyone. I tried laying on the bed with it in place, and it was OK, but since I am short, I think I would just tuck it into place on the far side of the bed for storage and sleep on the bed without the bolster..
4) The slide CAN be closed with or without the bolster in place. All of the top wardrobe doors are accessible, and one drawer is accessible. Ditto for bathroom being accessible.
5) Kitchen and refrigerator are completely accessible, which is good.
I took the motorhome for a test drive and did fine, which made me feel more comfortable. It drove "like a truck" but I guess that is to be expected. No swaying or instability.
I think this is the one I really want. Now I need to talk to my credit union this week about financing. They quoted me a price on a unit that had in stock which includes removing the dinette. It has almost everything I want, and one option I really don't care about, plus the extra paint option, which I can live with. I need to decide if I want to take this one, or order a unit minus the paint, which would save me some money. Paint, however, does have some value since it protects finish, so still more thinking to do. I still have some time before June 1.
